１０・・・横スタビライザーFigure 1 is a perspective view of a longitudinally stable laser resonator structure without a resonator; Figure 2 shows that the vertical min-up time is significantly reduced or eliminated, allowing active control, e.g. A resonant system can be constructed in which frequency modulation for causing the oscillation can also be eliminated. This means that a constant frequency laser without frequency modulation can be produced at relatively low cost. The coefficient of thermal expansion of the ceramic can also be matched to the structure of the resonator of the laser design by using a lithium aluminum silicate ceramic as described in German Patent No. L67L115. [Embodiments] Laser resonators are shown in embodiments of the drawings and will be described below. The resonant elements (3, 3a), for example prisms, mirrors and/or translucent mirrors, are mounted on two supports (1, 2), which are arranged on vertical stabilizers. They are connected by a barrel rod (5). The support and the rod are made of ceramic material. In the case of a folded resonator, FIG. 3 is a plan view of a laser resonator that is folded in a stable manner; FIG. . ■, 2... Support 3.3a... Resonant element 5... Vertical stabilizer 10...
